The microstructure and mechanical properties of Cu50Zr50−x Ti x (2.5 ≤ x ≤ 7.5) glass matrix composites have been investigated. The presence of austenitic (Pm-3m)/martensitic phases (P21/m and Cm) enhances the plastic deformability significantly. These composites show high yield strength up to 1753 MPa and large plastic strain over 15 pct. Their high strength scales with the volume fraction of glassy matrix and crystalline phase. When the austenitic phase forms instead of the martensite, the work hardening of the composite material increases.
